Marine diesel and gas engines are among the most efficient prime movers. But a
substantial part of the energy in the fuel is usually discarded as waste heat in the
exhaust gas and the cooling water. Recovering this otherwise wasted energy can
be an attractive proposition. The recovered low-temperature heat can have many
applications, including warming accommodation areas, de-icing decks and stair-
ways, and tank heating.
IMproVED SHIp EFFICIENCy THroUGH WASTE HEAT rECoVEry
Ulmatec Pyro is a leading manufacturer and supplier of heating and waste
treatment systems for the marine industry. Its highly skilled organisation aims
to be the best at serving the customer.
Know-how in Ulmatec Pyro builds on experience and customer feedback from as
far back as 1951, when it was founded. More than 15 000 ships worldwide have
been equipped with Pyro™ heating systems to date.
ULMATEC
By recovering waste energy, the marine industry can avoid burning fuel to generate heat. The annual savings can be substantial:
� 100 kW electrical heating = 200 000 l fuel � 100 kW fuel-fired heating = 100 000 l fuel � 100 kW heating by heat recovery = 0 l fuel
For every 1 000 kW of energy supplied to a diesel engine, only 300 kW will normally be used to drive the ship. At least 600 kW of the energy produced is lost through exhaust gas and cooling water. In other words, only 30% of the energy is used efficiently.
Pyro heat recovery systems exploit this lost energy for other applications. That means up to 60% of the energy produced can be utilised, giving a financial and environmental gain.

pyro™ CENTrAL HEATING SySTEM
The Pyro™ central heating system is both effective and flexible, providing substantial cuts in fuel consumption
and utilising “green” energy from waste heat. The latter is fully exploited for accommodation heating and other
consumers before needing to use high-grade primary energy in the form of oil or gas.
USES CoNVENTIoNAL FUEL oNLy WHEN “GrEEN” ENErGy IS INSUFFICIENT/UNAVAILABLE
� Optimum waste heat recovery.
� Heat recovered at different temperature levels.
� Minimal use of primary energy for top-up.
� Automatically pre-heated standby engines to
reduce wear and tear (pre-heating temperature at
several levels).
Flexibility
� Payback time likely to be less than a year
� Substantial cut in emissions
� Easy to design
� Easy to install
� Easy to operate
� The Pyro™ central heating system consists of
products such as exhaust gas economisers and
fuel-fired heaters and heat exchangers, plus an
advanced and flexible PLC-based control system to run
the advanced flow control unit and all other system
components.
� This system is based on a primary thermal fluid
circuit, comprising flow and return pipes and a
circulating pump module.
� Pyro™ central heating systems are well suited both
for newbuilds and for upgrading existing ships.
� For upgrading projects, Ulmatec can supply
complete packages of engineering, production and
installation.
� The Pyro™ central heating system is type-approved
by the main classification societies for the (EO)
notation.

� The key to the Pyro™ solution is that heat
suppliers and consumers are all connected as parallel
links between the flow and return sides of the primary
circuit, and each has its own control valve. That yields
a significant reduction in pipe dimensions.
� The system can also be designed in a flexible serial
and/or parallel combination, utilising heat recovery
from the high-temperature (HT) and exhaust gas
systems. That provides the opportunity to supply more
energy and/or higher temperatures to part or all of
the consumer system.
� Each consumer/consumer group is separately
supplied with the flow needed to provide the
required amount of heat.

pyro™ TANk HEATING SySTEM
Pyro™ tank heating systems exploit “green energy” from heat recovery in high-temperature (HT) cooling
systems and/or exhaust gas economisers in the exhaust gas system. Heating elements in the tank comprise
small high-performance heating coils. Pyro™ heating coils are designed for fast and easy mounting and
dismantling.

LoW INSTALLATIoN AND opErATING CoSTS
� The Pyro™ tank heating system has also been
developed for offshore support vessels equipped with
tank capacity for recovered oil, and meets Nofo 2009
standards. The system uses waste heat to provide ORO
tank heating, thereby saving fuel and reduce installed
capacity for fuel fired heater.
� With no steam required and utilising “green
energy” from the heat recovery system, the system has
low operating costs and emissions.
� Fast and easy mounting and dismantling of
heating coils when not in use.
No steam required for oro
� Closed pressurised heating system for marine
installations based on thermal fluid (water) circulation
and a working temperature up to 100°C.
� Working pressure normally 3 bar.
� Automatically controlled and monitored by a
control system, and can be interfaced to the main
computer system (IAS). Manual control is a standard
feature.
� Complies with Nofo 2009 standard and the OILREC
class notation.
� Significant reduction in installation cost.
� No need for complex piping systems.
� Small heating coil fitted in each tank close
to the discharge pump suction line heats tank
contents efficiently.

pyro™ FUEL-FIrED HEATErS
Ulmatec Pyro offers fuel-fired heaters designed for the marine environment. An optimum combustion
technology makes these units a cost-efficient and environment-friendly choice.
HIGH oUTpUT – FULLy AFTEr-BUrNING
� The Pyro™ fuel-fired heater for use with oil and
liquefied natural gas (LNG) is a smoke-tube type,
which ensures full afterburning within the furnace in
the first return of the exhaust gas.
� After the second return, the exhaust gas enters the
smoke tubes for its energy to be utilised.
� SERIES 1 – Oil-fired, 7 kW
� SERIES 2 – Oil- and gas-fired, 23–35 kW
� SERIES 3 – Oil- and gas-fired, 58–105 kW
� SERIES 4 – Oil and gas fired, 123–290 kW
� SERIES 5 – Oil- and gas-fired, 406–1 162 kW
� SERIES 6 – Oil- and gas-fired, 1 453–3 500 kW
� All-welded boiler steel.
� Electrical heating element can be integrated in the
heater for standstill heating or booster effect.
� Insert coils to generate sanitary hot water (SHW)
for domestic use.
� Doors for cleaning and inspection.
Ulmatec pyro™ fuel-fired heaters – range
� High output smoke-tube type
� Fully after-burning
� Easy service
� Easy to operate
� Easy to install
� Easy to design into a system
� Pyro ™ fuel-fired
heaters have a capacity
range from 7–3 500 kW
� All comply with
regulations from the
major classification
societies, and the control
system has been
type-approved by DNV,
LRS and ABS.

pyro™ ExHAUST GAS ECoNoMISEr
Installing a Pyro™ exhaust gas economiser cuts operating
costs and emissions. Depending on size and heating
requirements, the investment can be recovered within a
couple of years or even as quickly as a few months.
� Pyro™ exhaust gas economisers are all-welded
smoke-tube hot water generators designed for water
temperatures up to 120°C and a maximum working
pressure of 3 bar.
� Can be delivered as single-engine, multi-engine or
combination types, covering a wide range.
� Supplied in various sizes and capabilities in accordance
with total heat requirement and available waste heat.
� Advanced computer programmes ensure correct data
for dimensioning and for environment-friendly use of
energy.
� Can be supplied in special versions for inclined or
horizontal installation.
MATCHING CUSToMEr rEQUIrEMENTS
proTECTING THE ENVIroNMENT – SHorT pAyBACk TIME
� Water temperature is automatically controlled by a
specially designed valve, which diverts the gas flow
through a bypass when the temperature reaches the
pre-set level.
� This means that only part of the exhaust gas flow
is used, depending on demand. That reduces the
physical size of the boiler, allowing requirements to be
met in an optimum way.
� Opting for Pyro™ exhaust gas economisers
protects the environment, cuts operating costs and
provides a very short payback time.
� By using exhaust gas heat from the main and/or
auxiliary engines, an exhaust gas economiser will
provide heating under normal operating conditions
for accommodation areas, hot water, evaporators, oil
preheating and so forth.
� Eliminates acid corrosion problems caused by
extremely low temperature in exhaust gas system.
� To simplify cleaning and service, Pyro™ exhaust
gas economisers are fitted with removable plugs,
inspection holes and equipment for dosing with
special chemicals.
